RE: [EXTERNAL] RE: Closets and Clearance from Deflector to Storage
That is a great reason why you want to get your system water tight asap. When a soaked worker comes out of the closet with a soldering torch and a story about a sprinkler that "went off for no reason" - you will have a heads up before you spend hours trying to find an open outlet.

Re: [EXTERNAL] RE: Closets and Clearance from Deflector to Storage
The committee discussion on this change was the in a 400 cubic foot enclosure, it doesn’t matter where the sprinkler is relative to the shelf. Think about in rack sprinklers and the product loads…. I agree there should be concern for bumping the sprinkler but no one is loading the closet with a forklift so….

RE: Closets and Clearance from Deflector to Storage
My understanding had always been this was mainly related to shelves and the like as an obstruction since the head is going to basically inundate the closet. I believe it was Mr. Huggins that once reminded us that water isn't like light and you don't have to see the head to get wet, as was a popular method of evaluating obstructions on the enforcement side at the time. FWIW 9.5.6.6.1 is worth a look as it could apply to most closets I can think of as long as the head location was right.
